This paper presents the speed control of a separately excited DC motor using Fuzzy Logic Control (FLC). The Fuzzy Logic Controller designed in this study applies the required control voltage based on motor speed error (e) and its change (ce). The performance of the driver system was evaluated through digital simulations using Simulink. The simulation results show that the control with FLC outperforms PI control in terms of overshoot, steady state error and rise time. Topics: DC motor, chopper, FLC.

This paper proposes a method of minimization of torque ripple in Brushless DC (BLDC) motor with ideal back EMF under MATLAB 7.1/Simulink environment. An idealized BLDC motor has trapezoidal back EMF waveform. However, for practical reasons like non-uniformity of magnetic material and design parameters it is difficult to produce exact trapezoidal wave shape. Therefore torque ripple appears in conventional control. This paper, introduces the Hysteresis Current Control (HCC) method to minimize the...

This work represents a mathematical analysis and simulation of dc-motor electric drive control system with variable moment of inertia. A separately-excited dc motor is used in this control system. A mathematical model for this motor has been simulated and tested in Matlab/Simulink. A closed-loop control system for this dc electric drive system is proposed. The proposed control system is based on the technical optimum method of design. The controlled variable of this system is the load angular...

Abstract This paper presents comparison between full order and minimum order observer controller design using MATLAB environment. As a matter of fact, it has shown how to implement a dc motor state space model and its observer. Different observer gain(s) are determined by selecting different Eigen values for the observers. Both designed controllers are tested using root locus method by varying different observer poles. Having full understanding of the observer controller implementation(s),...

Among alternate sources of electricity, Solar Photo Voltaic (PV) energy is gaining prominence due to its plentiful availability. Water pumping is an important application of solar PV power. However people are not opting for it in large numbers as the ‘cost per watt’ for solar pumping systems is high. The cost can be reduced by harnessing more power per unit installed capacity of the solar panel. One method of realising this is by Maximum Power Point Tracking (MPPT) wherein a power...

Brushless DC (BLDC) motors are attaining higher priority in industrial automation, computers, aerospace, military, household appliance and traction applications because of its high efficiency, high power density and low maintenance cost. To control a BLDC machine, it is generally required to measure the speed and position of rotor by using the sensor. Using the measured value of rotor position, each inverter phase acting at precise time will be commutated. This paper presents a simple digital...
